Description
BACKGROUND
Field of Invention
The present invention relates to a displaying apparatus. More
particularly, the present invention relates to a 2D/3D image
displaying apparatus.
Description of Related Art
For a conventional display for displaying three-dimensional (3D)
images, it usually produces binocular disparity by temporally or
spatially multiplexing left and right views. However, temporally
multiplexing views easily causes images to flicker, and spatially
multiplexing views easily causes resolution of images to
deteriorate.
On the other hand, for a conventional display for displaying
two-dimensional (2D) images, in order to solve problems about
viewing angles, a liquid crystal display with multi-domain vertical
alignment (MVA) technique is developed. In the MVA liquid crystal
display, a liquid crystal area is divided into multiple areas so
that liquid crystal molecules incline to multiple directions to
increase viewing angles of the liquid crystal display. Moreover, in
order to further solve problems about color wash-out in the MVA
liquid crystal display, prior arts also provide several
solutions.
However, for the present art, the liquid crystal displays are
mostly provided for processing only 3D or 2D images so as to solve
respective problems. Thus, it is necessary to provide a displaying
apparatus capable of selectively displaying 2D or 3D images and
solving the foregoing problems of displaying 2D and 3D images in
the meantime.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the following detailed description, the embodiments of the
present invention have been shown and described. As will be
realized, the invention is capable of modification in various
respects, all without departing from the invention. Accordingly,
the drawings and description are to be regarded as illustrative in
nature, and not restrictive.
FIG. 1 illustrates a two-dimensional/three-dimensional (2D/3D)
image displaying apparatus according to an embodiment of the
present invention. The 2D/3D image displaying apparatus 100
includes a plurality of data lines (e.g. D1, D2, . . . ), a
plurality of scan lines (e.g. G1, G2, . . . ), a data driving
circuit 102, a gamma circuit 104 and a pixel array 110, in which
the pixel array 110 is defined by intersecting the data lines D1,
D2, . . . and the scan lines G1, G2, . . . , and the gamma circuit
104 is configured for transmitting gamma signals to the data
driving circuit 102, so as to drive the pixel array 110 through the
data lines D1, D2, . . . by the data driving circuit 102, such that
the pixel array 110 displays images according to data transmitted
through the data lines D1, D2, . . . .
In the present embodiment, the pixel array 110 includes a plurality
of pixels 111, and each of the pixels 111 includes a plurality of
sub-pixels 112 which can be red, green or blue. In addition, each
sub-pixel 112 includes a first portion 112a and a second portion
112b, and the first portion 112a and second portion 112b of the
sub-pixel 112 are separately coupled to the corresponding data
lines and coupled to the corresponding scan line together.
Specifically, in FIG. 1, the first portion 112a and second portion
112b of the sub-pixel 112 at the 1.sup.st column and 1.sup.st row
are separately coupled to the corresponding data lines D1 and D2
and also coupled to the corresponding scan line G1 together. For
the sub-pixel 112 on the same row and adjacent to the sub-pixel 112
at the 1.sup.st column and 1.sup.st row, its first portion 112a and
second portion 112b are separately coupled to the corresponding
data lines D3 and D4 and also coupled to the corresponding scan
line G1 together. For the sub-pixel 112 on the same column and
adjacent to the sub-pixel 112 at the 1.sup.st column and 1.sup.st
row, its first portion 112a and second portion 112b are separately
coupled to the corresponding data lines D1 and D2 and coupled to
the corresponding scan line G2 together. The rest of sub-pixels 112
may be deduced by analogy. Therefore, it can be seen that each
sub-pixel 112 is coupled to two data lines and one scan line.
Moreover, in one embodiment, a ratio of the size of the first
portion 112a to the size of the second portion 112b is
approximately 1:1. However, persons skilled in the art can adjust
the ratio in practice.
When the 2D/3D image displaying apparatus 100 displays 2D images,
the gamma circuit 104 transmits gamma signals to the data driving
circuit 102 such that the data driving circuit 102 separately and
dependently drives the first portion 112a and the second portion
112b of each sub-pixel 112 through the data lines D1, D2, . . . .
Specifically, when 2D images are displayed, the gamma circuit 104
transmits different gamma signals having dependent relationships
therebetween to the data driving circuit 102, such that the first
portion 112a and the second portion 112b of each sub-pixel 112 are
driven by the data driving circuit 102, resulting in that the
corresponding first portion 112a and second portion 112b display
images with different illumination. For example, when the sub-pixel
112 is about to display the image having a certain gray level, the
gamma circuit 104 would transmit different but matching gamma
signals to the data driving circuit 102, such that gray-level
images displayed by the first portion 112a and the second portion
112b are just matched to be the gray-level images which the
sub-pixel 112 is about to display, even if the first portion 112a
and the second portion 112b display different gray-level
images.
On the other hand, when the 2D/3D image displaying apparatus 100
displays 3D images, the gamma circuit 104 transmits gamma signals
to the data driving circuit 102 such that the data driving circuit
102 separately and independently drives the first portion 112a and
the second portion 112b of each sub-pixel 112 through the data
lines D1, D2, . . . . Specifically, when 3D images are displayed,
the gamma circuit 104 transmits a single gamma signal to the data
driving circuit 102, such that the first portion 112a and the
second portion 112b of each sub-pixel 112 are driven by the data
driving circuit 102, resulting in that the corresponding first
portion 112a and second portion 112b display different and
independent gray-level images.
The 2D/3D image displaying apparatus 100 further includes a
patterned optical phase retarder 120 which is selectively arranged
corresponding to the first portions 112a or the second portions
112b of the sub-pixels 112, so as to modulate the light passing
through the first portions 112a or the second portions 112b. In the
present embodiment, the patterned optical phase retarder 120 is
exemplarily arranged corresponding to the first portions 112a of
each row of the sub-pixels 112, as shown in FIG. 1, so as to
modulate the light passing through the first portions 112a, such
that the first portions 112a can produce different polarization
from that of the second portions 112b and display desired
images.
FIG. 2 illustrates a block diagram of the 2D/3D image displaying
apparatus according to one embodiment of the present invention. The
2D/3D image displaying apparatus 200 includes a splitter 202,
timing controllers 204a and 204b, drivers 206a and 206b, a display
panel 208 and a gamma circuit 210, in which the display panel 208
can include the data lines, scan lines and pixel array as shown in
FIG. 1, and the timing controllers 204a and 204b or the drivers
206a and 206b can be integrated into a single circuit for
processing signals. After receiving and distributing a TV video
signal with full high definition (FHD) and a frequency of 120 Hz,
the splitter 202 transmits the processed signals to the timing
controllers 204a and 204b respectively. Then, the drivers 206a and
206b are controlled respectively by the timing controllers 204a and
204b and separately transmit data to the display panel 208
according to the processed signals received from the timing
controllers 204a and 204b and different gamma signals (or gamma
voltages) A and B transmitted from the gamma circuit 210,
respectively, such that the display panel 208 is capable of
displaying 2D images with a frequency of 120 Hz without causing
color wash-out problems.
FIG. 3 illustrates a block diagram of the 2D/3D image displaying
apparatus according to another embodiment of the present invention.
The 2D/3D image displaying apparatus 300 includes a mixer 302, a
splitter 304, timing controllers 306a and 306b, drivers 308a and
308b, a display panel 310 and a gamma circuit 312, in which the
display panel 310 can include the data lines, scan lines and pixel
array as shown in FIG. 1, the timing controllers 306a and 306b or
the drivers 308a and 308b can be integrated into a single circuit
for processing signals, and the gamma circuit 312 can be the same
as the gamma circuit 210 as shown in FIG. 2. After receiving and
superimposing a left-eye and right-eye video signal with full high
definition (FHD) and a frequency of 60 Hz, the mixer 302 transmits
the processed signals to the splitter 304. Then, after receiving
and distributing the signal from the mixer 302, the splitter 304
transmits the processed signals to the timing controllers 306a and
306b respectively. After that, the drivers 308a and 308b are
controlled respectively by the timing controllers 306a and 306b and
transmit data to the display panel 310 according to the processed
signals received from the timing controllers 306a and 306b and
single gamma signal C transmitted from the gamma circuit 312, such
that the first portions and second portions of the sub-pixels in
the display panel 310 are capable of respectively displaying
left-eye and right-eye 3D images with frequency of 60 Hz, for users
wearing polarized glasses to view the 3D images displayed on the
display panel 310, without causing resolution of 3D images to
deteriorate.
FIG. 3A illustrates the switch of gamma signals outputted by the
gamma circuit operating under 2D and 3D image modes according to
one embodiment of the present invention. As shown in FIG. 3A, when
the gamma circuit operates under the 2D image mode, the gamma
circuit outputs different gamma signals A and B having dependent
relationships therebetween, such that the driving circuit can
separately drive the first portions 112a and the second portions
112b of the sub-pixels 112 according to the different gamma signals
A and B, and the first portions 112a and the second portions 112b
of the sub-pixels 112 display the images corresponding to the gamma
signals A and B having dependent relationships therebetween, to
solve color wash-out problems. The gamma signal D represented by
the dotted line is equivalent to the ultimately outputted gamma
signal (corresponding to the gray-level image on the display screen
and viewed by human eyes) after the gamma signals A and B are
superimposed. On the contrary, when the gamma circuit operates
under the 3D image mode, the gamma circuit outputs single gamma
signal C, such that the driving circuit can separately drive the
first portions 112a and the second portions 112b of the sub-pixels
112 according to the gamma signal C, and the first portions 112a
and the second portions 112b of the sub-pixels 112 separately
display different and independent images according to the gamma
signal C, to prevent from deteriorating resolution of 3D
images.
In other words, when the display device operates under 2D and 3D
image mode respectively, the switch between 2D and 3D image modes
can be performed by using a programmable gamma circuit or gamma IC
to transmit required gamma signals corresponding to 2D or 3D images
to the driving circuit, for the display device to display 2D or 3D
images.
On the other hand, for the timing controllers shown in FIGS. 2 and
3, they transmit timing control signals with different frequencies
to the driving circuit when 2D and 3D images are displayed
respectively, so as to control the driving circuit. In one
embodiment, the frequency of the timing control signal transmitted
by the timing controller when the 2D image is displayed is larger
than the frequency of the timing control signal transmitted when
the 3D image is displayed. Taking the embodiments in FIGS. 2 and 3
for example, the timing control signal transmitted by the timing
controller when the 2D image is displayed is two times the
frequency of the timing control signal transmitted when the 3D
image is displayed. As a result, the displaying apparatus can
separately display 2D images with frequency of 120 Hz or 3D images
with frequency of 60 Hz by being switched to operate with different
frequencies.
Moreover, in another embodiment, the foregoing splitter 304 further
can transmit the processed signals to the timing controllers 306a
and 306b respectively for follow-up process after distributing one
multi-view image signal, such that the first portions and the
second portions of the sub-pixels in the display panel 310
separately display the corresponding portions of the multi-view
image, for viewers with naked eyes to view the displayed 3D images
on the display panel 310. Therefore, the foregoing embodiments in
FIGS. 2 and 3 are employed with different data streaming manners to
respectively transmit different frame data to different regions of
each sub-pixel, to further achieve the effect of enhancing
resolution of images.
Thus, when the 2D/3D image displaying apparatus in the embodiment
of the present invention has the display panel shown in FIG. 1, the
2D/3D image displaying apparatus can include the circuits shown in
FIGS. 2 and 3 and can switch when displaying 2D or 3D image, so as
to process the 2D or 3D image data.
FIG. 4 illustrates a pixel array according to another embodiment of
the present invention. Compared to FIG. 1, the pixel array 410
includes a plurality of pixels 411, each of which further includes
a plurality of sub-pixels 412, and each sub-pixel 412 includes a
first portion 412a and a second portion 412b, in which a ratio of
the size of the first portion 412a to the size of the second
portion 412b can be approximately 1:1, in which persons skilled in
the art can adjust the ratio in practice, and the first portion
412a and the second portion 412b can be separately coupled to the
corresponding scan lines and coupled to the corresponding data line
together.
Specifically, in FIG. 4, the first portion 412a and the second
portion 412b of the sub-pixel 412 at the 1.sup.st column and
1.sup.st row are separately coupled to the corresponding scan lines
G1 and G2 and coupled to the corresponding data line D1 together.
For the sub-pixel 412 on the same column and adjacent to the
sub-pixel 412 at the 1.sup.st column and 1.sup.st row, its first
portion 412a and second portion 412b are separately coupled to the
corresponding scan lines G3 and G4 and also coupled to the
corresponding data line D1 together. For the sub-pixel 412 on the
same row and adjacent to the sub-pixel 412 at the 1.sup.st column
and 1.sup.st row, its first portion 412a and second portion 412b
are separately coupled to the corresponding scan lines G1 and G2
and coupled to the corresponding data line D2 together. The rest of
sub-pixels 412 may be deduced by analogy. Therefore, it can be seen
that each sub-pixel 412 is coupled to two scan lines and one data
line.
As a result, the first portions 412a and the second portions 412b
in the pixel array 410 also can be analogous to the first portions
112a and the second portions 112b in FIG. 1 and display
corresponding 2D or 3D images according to the driving circuit and
its operations. Similarly, the 2D/3D image displaying apparatus 400
can further include a patterned optical phase retarder (not shown)
which is selectively arranged corresponding to the first portions
412a or the second portions 412b of the sub-pixels 412, so as to
modulate the light passing through the first portions 412a or the
second portions 412b.
Based on the concepts in FIGS. 1 and 4, a single sub-pixel further
can be designed to include a plurality of portions. FIG. 5
illustrates a single sub-pixel according to yet another embodiment
of the present invention. The sub-pixel 512 can be red, green or
blue. Compared to the sub-pixel in FIGS. 1 and 4, the sub-pixel 512
in the present embodiment includes a plurality of portions 516
which are defined by intersecting a plurality of (e.g. M) data
lines and a plurality of (e.g. N) scan lines; that is, each
sub-pixel 512 is coupled to M data lines and N scan lines and has a
plurality of portions 516, and the sizes of the portions 516 can
all be approximately the same.
Notably, although the multiple portions of the sub-pixel shown in
FIGS. 1, 4 and 5 are exemplarily illustrated as quadrangles, they
can be designed as triangles or other shapes in practice by persons
skilled in the art and not limited to the shapes illustrated in
FIGS. 1, 4 and 5.
For the foregoing embodiments of the present invention, the 2D/3D
image displaying apparatus can be employed to not only improve the
color wash-out when the displaying apparatus displays 2D images but
also enhance resolution of 3D images displayed on the displaying
apparatus when the displaying apparatus displays 3D images.
As is understood by a person skilled in the art, the foregoing
embodiments of the present invention are illustrative of the
present invention rather than limiting of the present invention. It
is intended to cover various modifications and similar arrangements
included within the spirit and scope of the appended claims, the
scope of which should be accorded the broadest interpretation so as
to encompass all such modifications and similar structures.
